| 摘 要： | 养马岛西南海域近30年来发生普遍淤积，海域海底淤积速率平均为1．5cm／a，局部可达10cm／a。鱼鸟河以东岸线向海推进速度约1～6m／a。海域表层沉积物有整体细化的趋势，该海域的快速淤积与海岛的屏蔽消能以及海堤的拦截作用有关。海底淤积对取水口的设计方案有明显影响，分析了工程海域动力、泥沙、海岸及近岸演化态势，并对取水口设计方案进行了论证。

| Abstract: | A general siltation occurred in the sea area southwest of Yangma Island in the past 30 years, and the mean bottom accretion rate in the area was 1.5 cm/a with an accretion rate up to 10 cm/a in some area. The progradation rate of coastline east of the Yuniao River was about 1 to 6 m/a. The surficial sediment in the sea area has a trend to become finer, and the quick siltation in the sea area is related to the energy dissipation due to the island shield and the seawall blocking. The bottom accretion has obvious effect on the design plan of water intake. In this paper, the hydrodynamics, sediment transport and nearshore evolution situation in the sea area are analyzed, and the design plans of water intake are also discussed. |
